Application mea octtber 2, 1919. serial 110.328,016;

To all whom tv/tay concern.' Y

Be it known that I, Jn'ss'n T.'Hor1i1Ns, a citizen of the United States,residing at Kansas City, in thecounty of Jackson and State of Missouri,have invented' a certain new and usefulV Improvement in Clamping Tools,of which the following is a specification. V

My invention relates to improvements in.

proved fastener, shown applied to a hose.

Fig'. 2 is a perspective view of the two clamping members, which may beemployed to hold the fastener and hose under compression when thefastener is being applied.

Fig. 3 is a plan view of the metal fastening strip in stretched outform.

Fig. 4 is a cross section on the line 4*-4 of Fig. 1.

Fig. 5 is a cross section showing the clamping members held undercompression by the pliers against the fastening strip.

Fig. 6 is a cross section of the plier handles taken on the line 6 6 ofFig. 7, showing the fastening strip clamped by the plier handles in theformation of the bridge.

Fig. 7 is perspective view, partly broken away, of the pliers whichmaybe used for holding the clamping plates and forraising the bridge in thestrip.

Similar reference characters designate similar parts in the differentviews.

1 designates the fastening strip which may be a strip of flexible sheetmetal adapted to be tightly wrapped around an ordinary hose 2 forattaching the same to a tubular member, such as a hose coupling member3. j

The strip 1 is provided with a longitudinal row of transverse slots 4,through two adjacent ones of which the reduced end 5 of the strip isadapted to be inserted.

In attaching the hose 2 to a coupling member 3, the strip 1 is boundtightly around the hose and thecoupling member 3, the reduced end 5 ofthe strip being inserted through t-wo of the slots 4 and under a bridge6 which has been raised between said two slots. The reduced end is thenbent into a return bend, Figs. 1 and 4, thereby securely holding thestrip 1 in position with the hose 2 compressed tightly against thecoupling member 3.

For compressing the. strip 1 and the h'ose 2 when the strip is beingapplied to the hose,'IA provide two substantially semi-circularclampingv plates 7 and 8, Figs. 2 and 5, which are provided respectivelywith two' end slots 9 and 10, adapted to receive the reduced end 5, ofthe strip 1.

For forcing the clamping members 7 and 8 toward each other, IV provide apair of pliers having two jaws 1I and 12, provided respectively withhandles 13 and 14.

For raising the bridge 6 in the strip, the handle 18 is provided with araised portion 15 adapted toforce the bridge portion 6 into atransversevslot 16 on the inner side of the handle 14. v

In applying the fastener to a hose, the plier handles are first employedto raise the bridge 6 between two of the slots 4, such two slotsdepending upon the diameter of the hose.

The strip 1 is then wound around the hose bend ever the bridge 6,thereby locking the strip against the hose 2 with the latter tightlycompressed on the member 3. The pliers and clamping members 7 and 8 maythen be removed.

- The slots 9 and 10 permit the portion 5 to be folded over into thereturn bend. It will be noted that when the clamping members 7 and 8 arecompressed to the limit,

they will embrace the strip 1 along. the substantially fullcircumference of the hose 2, thereby holding the strip and hose undercompression along the entire circumference, the clamping members beingeach a semicircle. After the return bend has been made in the strip 1,and the clamping members removed, there will be no slack in the strip l,and the hose will remain tightly clamped under the original amount ofclamping pres- Sllle.

I do not limit my invention to the strueture shown and described, asmoditications7 Within the scopeof the appended claims,

may be made Without departing from the spirit of my invention.

VWhat I claim is In a clamping tool, tvvo clamping members adapted toembrace and hold under compression along vthe substantially inllcircumference oi" a hose a flexible metal strip, one of said membershaving a slot adapted to rceeive therethrough one end of the strip, andmeans for forcing said clamping members toward each other, substantiallyas set forth.

2. In a clamping tool, two'substantially semi-circular clamping membersadapted to embracev a strip around a hose, one of the members having aslot adapted to receive the strip, and a pair of pliers having twok jawseach member will abut against the ends oi` the other member when themembers are in the clamping position, and means for foreing said membersto and for holding them in the clamping position, substantially as 't Ai V40 set forth.

In testimony whereof I have signed my name to this specication. Y
